The Versatility of our Magnetic Shielding Alloy Mumetal

Magnetic Shielding Alloy Mumetal November 12, 2018

Have a Magnetic Shielding Alloy Mumetal problem? If you are at all familiar with our company, you know that our products are generally used in fairly high-tech commercial endeavors. The most common places that you may see MuShield products at work are in:

  • Aerospace
  • Medical devices
  • Military
  • Utilities
  • Airport security scanners
  • GPS Communications

But sometimes, when you have a product so versatile and practical as our magnetic shielding alloy mumetal, you find that the applications become almost infinite.

Recently, we’ve come to discover that mumetal has gained quite the fanfare in the world of hobbyists – most notably, those who build and fly drone aircraft. It seems that mumetal is the perfect magnetic shielding material to help improve accuracy and control in these remote-controlled aircrafts.

Intrigued by this, we decided to investigate a bit to see how these clever folks were using our product, and how this new hype came to be.

We first came upon a YouTuber who’s channel Painless 360 had aired a video entitled: “RC Quick Tips: What is mumetal?” Immediately we noticed that the video had already been viewed over 17,000 times, clear reaffirming that mumetal had indeed taken on quite the notoriety within this circle. The video demonstrated how this pilot had used mumetal to block magnetic interference produced by high electrical currents in the power distribution board of his aircraft. Seeing as though small radio-controlled aircrafts such as drones have their electrical componentry crammed into very small spaces, this made perfect sense. On most aircraft of this type, the flight control module sits above or very near to the power board. As interference runs from the power board up through the flight controller it can create significant disturbance in the magnometer. When this occurs, GPS functions are compromised, and the aircraft will begin to “toilet bowl,” or swirl, due to the fact that it cannot properly lock-on to magnetic north. By installing a small piece of mumetal magnetic shielding alloy between the power distribution board and the flight controller, this ingenious hobbyist was able to block magnetic interference and greatly improve the performance of his aircraft. We were impressed.

Next, in a couple hobby forums, we saw a few mentions of mumetal being implemented to control RF noise produced by HD cameras mounted on drone aircraft. It seems a number of hobbyists have discovered that they can not only use this material for EMI shielding, but in RF shielding as well. By fabricating a small box of mumetal to house the camera, high frequency fields emitted by the camera were blocked, thus again enabling the aircraft to operate properly without disturbance to the GPS system.

We guess it goes to show, when you design and manufacture great products, you never know how many people and industries you will have the honor of benefitting. It’s inspiring to know that we can help improve the performance of equipment from laboratories of the International Space Station (link to Cold Atom Laboratory article) to airport security, to drones.
